Hydroxypropylmethylcellulose (HPMC) ndi polima yosunthika yomwe imagwiritsidwa ntchito kwambiri pantchito yomanga. Ndizinthu zopanda poizoni, zopanda fungo, pH-zokhazikika zomwe zimapangidwa poyambitsa magulu a hydroxypropyl ndi methyl mu cellulose yachilengedwe. HPMC imapezeka m'makalasi osiyanasiyana okhala ndi ma viscosities osiyanasiyana, kukula kwa tinthu ndi magawo olowa m'malo. Ndi polima yosungunuka m'madzi yomwe imatha kupanga ma gels pamalo okwera kwambiri koma imakhala ndi zotsatira zochepa kapena zosakhudza kamvekedwe ka madzi pamiyeso yotsika. Nkhaniyi ikufotokoza za kagwiritsidwe ntchito ka HPMC muzomangamanga zosiyanasiyana.
Kugwiritsa ntchito HPMC pakupaka pulasitala ndi kupereka
Kumanga nyumba kumafuna kukonzanso kwapamwamba kwa makoma, pansi ndi kudenga. HPMC ndi anawonjezera gypsum ndi pulasitala zipangizo kumapangitsa workability awo ndi kumamatira. HPMC bwino kusalala ndi kusasinthasintha pulasitala ndi pulasitala zipangizo. Zimawonjezera mphamvu yosungira madzi ya zosakaniza, zomwe zimawathandiza kuti azitsatira bwino khoma kapena pansi. HPMC imathandizanso kupewa kuchepa ndi kusweka pakuchiritsa ndi kuyanika, ndikuwonjezera kulimba kwa zokutira.
Kugwiritsa ntchito HPMC pazomatira matailosi
Zomatira matailosi ndi mbali yofunika kwambiri pa ntchito zomanga zamakono. HPMC imagwiritsidwa ntchito pomatira matailosi kuti apititse patsogolo kumatira kwawo, kusunga madzi komanso ntchito yomanga. Kuonjezera HPMC pakupanga zomatira kumawonjezera nthawi yotseguka ya zomatira, kupatsa oyika nthawi yochulukirapo kuti asinthe matailosi asanakhazikike. HPMC imawonjezeranso kusinthasintha ndi kukhazikika kwa mgwirizano, kuchepetsa chiopsezo cha delamination kapena kusweka.
Kugwiritsa ntchito HPMC muzopanga zokha
Mankhwala odzipangira okha amagwiritsidwa ntchito kuti asamalire pansi ndikupanga malo osalala, osakanikirana poyika zipangizo zapansi. HPMC imawonjezedwa kumagulu odzipangira okha kuti apititse patsogolo kuyenda kwawo komanso kusanja kwawo. HPMC imachepetsa kukhuthala koyambirira kwa kusakaniza, kupangitsa kuti ikhale yosavuta kugwiritsa ntchito ndikuwongolera kuwongolera. HPMC imawonjezeranso kusungidwa kwa madzi kwa osakaniza, kuonetsetsa kuti mgwirizano uli wolimba pakati pa zinthu zapansi ndi gawo lapansi.
Kugwiritsa ntchito HPMC mu caulk
Grout amagwiritsidwa ntchito kudzaza mipata pakati pa matailosi, miyala yachilengedwe kapena zinthu zina zapansi. HPMC imawonjezedwa kumagulu ophatikizana kuti apititse patsogolo ntchito yake yomanga komanso kulimba. HPMC imawonjezera kukhuthala kwa kusakaniza, kupangitsa kuti ikhale yosavuta kufalitsa ndikuchepetsa kuchepa ndi kusweka kwa zinthu zodzaza panthawi yochiritsa. HPMC imathandizanso kumamatira kwa chodzaza ku gawo lapansi, kuchepetsa mwayi wa mipata yamtsogolo ndi ming'alu.
HPMC muzinthu zopangidwa ndi gypsum
Zinthu zopangidwa ndi gypsum, monga plasterboard, matailosi a padenga ndi matabwa otsekera, amagwiritsidwa ntchito kwambiri pantchito yomanga. HPMC imagwiritsidwa ntchito pazinthu za gypsum kuti ziwongolere magwiridwe antchito awo, kukhazikitsa nthawi ndi mphamvu. HPMC imachepetsa kufunikira kwa madzi pakupanga, kulola kuti zikhale zolimba kwambiri, zomwe zimawonjezera mphamvu ndi kulimba kwa chinthu chomalizidwa. HPMC komanso bwino adhesion pakati pa gypsum particles ndi gawo lapansi, kuonetsetsa mgwirizano wabwino.
Pomaliza
Hydroxypropylmethylcellulose (HPMC) ndi polima wosunthika wogwiritsidwa ntchito muzomangamanga zosiyanasiyana. HPMC imathandizira magwiridwe antchito a gypsum ndi pulasitala, zomatira matailosi, mankhwala odzipangira okha, ma grouts ndi zinthu zopangidwa ndi gypsum. Kugwiritsa ntchito HPMC muzinthu izi kumathandizira kukhazikika, kumamatira, kusunga madzi komanso kukhazikika. Chifukwa chake, HPMC imathandizira kupanga zida zomangira zolimba, zolimba, zokhalitsa zomwe zimakwaniritsa zofunikira zamamangidwe amakono.
